browser_vulnerabilities 0.1.0

Library for detecting vulnerable browsers

This small library detects vulnerable operating systems and browsers based on browser user-agent string. No active checks are included.

from browser_vulnerabilities import BrowserVulnerability

ua1 = 'Mozilla/5.0 (Windows NT 6.3; WOW64; rv:26.0) Gecko/20100101 Firefox/26.0'
ua2 = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:27.0) Gecko/20100101 Firefox/27.0'
bv = BrowserVulnerability(ua1)
print bv.vulnerabilities()
# {'priority': 'recommended', 'readable_version': 'Firefox older than 27.0',
# 'name': 'Firefox', 'version__smaller': '27.0'}
bv = BrowserVulnerability(ua2)
print bv.vulnerabilities()
# False

Minimal database is available in browser_vulnerabilities/data.py file. The database is updated manually. Order of criteria is important. The most important and most strict criteria should be first. Matching is aborted on the first hit.

Mandatory keywords:

• platform / flavor / name: first two are for OS, and name for browser (feature of httpagentparser)

• priority:

  • “mandatory” - user action is required, and actions should be either denied or delayed with message.

  • “recommended” - updating is highly recommended but not mandatory.

  • “optional” - the warning should be shown to user only when user requests more information.

Optional keywords:

• version__smaller: any version larger than this will not match the rule.

• version__larger: any version smaller than this will not match the rule.

• version__extra: compiled re for additional checks.

• vuln: link to related website describing the vulnerabilities / why specific update is important.

• readable_name: user-readable product name

• version: user-readable version criteria for warnings
